question about dip pen holder

Apologies for bothering you but i couldn't find any information on google about the specific issue I have with my francesco rubinato dip pen. So basically the nib holder is called 'universal mount'(See the pictures below) and the thing is it can rotate around the grip section, meaning that it can circle in it, i think it's easy to understand. Also the pen nib can get in, in multiple directions, which one is the right one to put it properly? I expect someone who has experience with this to help me and not someone just saying "putting the nib in any way is fine if it doesn't bother you". One way to help me is just by giving me advice while the other option is to just send me your own rubinato dip pen so i can see which way is the right one.

Thanks in advance and sorry for bothering but I really need to short this out. Find my pictures on google photos below.
